A kind of unpowered blade grinder
The present invention relates to tire equipment field, be specifically related to a kind of unpowered blade grinder for grinding tire cutter band.
Rubber slicing machine is that the banding knife-band using annular is to leather
Cutting into slices, the blade of knife-band can occur abrasion after long-term use or have leather to adhere to, and causes cutting efficiency to decline and cutting accuracy step-down.Blade grinder can be set in a certain position of the movement locus of knife-band on traditional rubber slicing machine, emery wheel by driven by motor, grinding edge to knife-band in knife-band work process.The defect of this emery wheel is, 1. needs driven by motor, and grinding force is big, and to knife-band grinding by force, fragile knife-band；2. when to the grinding simultaneously of the upper and lower surface of knife-band, need two emery wheels and two motors, take up room big.
Summary of the invention
It is an object of the invention to provide a kind of without power, simple in construction, the unpowered blade grinder on upper and lower two surfaces of grinding knife-band simultaneously.
For reaching object above, the technical scheme that the present invention takes is:
nullA kind of unpowered blade grinder，Including mounting seat，Described mounting seat includes base plate、Gripper shoe and emery wheel installing plate，Described base plate is provided with bolt hole，Described gripper shoe is vertically connected to end face on base plate，Described emery wheel installing plate is parallel to base plate and is installed on gripper shoe，The end face of described emery wheel installing plate is provided with multiple oblique through hole，The axis place plane of described oblique through hole is each perpendicular to gripper shoe，The axis of described oblique through hole and emery wheel installing plate upper surface be at an acute angle or obtuse angle angle，It is installed with sleeve in described oblique through hole，The inwall of described sleeve is provided with screw thread，In described sleeve, cross-under has adjusting screw rod，The end section of described adjusting screw rod is stepped，The bottom of described adjusting screw rod is provided with bearing，Described bearing end face is spacing by cascaded surface，Described bearing bottom surface through nut check in adjusting screw rod bottom，It is socketed with emery wheel on described bearing，It is provided with pad between the bottom surface of described emery wheel and nut，Fix through screw between described pad and emery wheel.
Further, including the oblique through hole of four conllinear, described four oblique through hole lines are parallel to gripper shoe.
Yet further, the axis of two oblique through holes and emery wheel installing plate upper surface angle at an acute angle, the axis of another two oblique through holes and emery wheel installing plate upper surface angle in obtuse angle in described four oblique through holes.
After taking above technical scheme, the invention have the benefit that the base plate of mounting seat is for being connected with rubber slicing machine, four emery wheels are adjusted screw rod and are installed on mounting seat, the wherein lower sword of two grinding knife-band, the upper sword of two grinding knife-band, four emery wheel intervals are arranged, adjusting screw rod tilts certain angle, make the grinding face of emery wheel fit grinding vertical with the upper and lower surface of knife-band blade all the time on screw rod, the size of the blade so ensured and angle, it is ensured that cutting precision；Emery wheel is bowl-type emery wheel, emery wheel is installed on the end of adjusting screw rod through bearing, during knife-band rotation work, frictional force is had to drive emery wheel to rotate and grinding simultaneously, without power, and grinding damage is little, and emery wheel is the most in running order, ensure that knife-band is always optimum state, improve precision and the efficiency of microtome.
Along with the abrasion of knife-band, the position of emery wheel needs regulation with knife-band of fitting, and uses adjusting screw rod can realize the up-down adjustment of emery wheel position, it is to avoid the adjustment repeatedly of mounting seat and location, affects quality and precision.

Detailed description of the invention
Below in conjunction with accompanying drawing, the detailed description of the invention of the present invention is further described:
As shown in the figure, a kind of unpowered blade grinder, including mounting seat 1, described mounting seat 1 includes base plate 11, gripper shoe 12 and emery wheel installing plate 13, the corner of described base plate 11 is respectively equipped with bolt hole 14, and described gripper shoe 12 is vertically connected to end face on base plate 11, and described emery wheel installing plate 13 is parallel to base plate 11 and is installed on gripper shoe 12, described base plate 11, gripper shoe 12 and the C-shaped setting of emery wheel installing plate 13, through one-body molded or be welded.The end face of described emery wheel installing plate 13 is provided with four oblique through holes 15, is installed with an emery wheel unit 2 in each oblique through hole.nullDescribed emery wheel unit includes adjusting screw rod 21、Sleeve 22、Adjustment disk 23、Emery wheel 24、Bearing 25、Nut 26，Pad 27、Boss cascaded surface 28 and locking nut 29，Described sleeve 22 is fixing to be welded in oblique through hole 15，The inwall of described sleeve 22 is provided with screw thread，In described sleeve 22, cross-under has adjusting screw rod 21，The locking nut 29 coordinated with sleeve it is connected with on described adjusting screw rod 21，The end section of described adjusting screw rod 21 is stepped，The bottom of described adjusting screw rod 21 is provided with bearing 25，Described bearing 25 end face is spacing by cascaded surface 28，Described bearing 25 bottom surface lock onto adjusting screw rod 21 bottom through nut 26，On described bearing 25 outer wall, emery wheel 24 is installed，Described emery wheel 24 is bowl-type emery wheel，It is provided with annular gasket 27 between the bottom surface of described emery wheel 24 and nut 26，The endoporus of described pad is less than the external diameter of nut，Fix through screw between described pad 27 and emery wheel 24.
The axis of described oblique through hole 15 is positioned in the plane both perpendicular to gripper shoe and base plate, and described four oblique through hole 15 conllinear, the line of described four oblique through holes 15 is parallel to gripper shoe 12.The axis of the oblique through hole of described two of which 15 and emery wheel installing plate 13 upper surface angle at an acute angle, the emery wheel 24 of the emery wheel unit 2 installed in this oblique through hole 15 contacts grinding with knife-band blade lower surface, the axis of two other oblique through hole 15 and emery wheel installing plate 13 upper surface angle in obtuse angle, emery wheel 24 and the knife-band blade upper surface grinding of the emery wheel unit 2 installed in this oblique through hole 15, the angle of described angle is relevant to knife-band blade upper angle and lower angle, and the angle of inclination of oblique through hole guarantees that wheel grinding surface is just vertical with the upper and lower surface of blade.
